移植minicom到OpenHarmony4.0

一. 下载minicom包和ncurses包

wget https://fossies.org/linux/misc/minicom-2.9.tar.bz2
wget https://ftp.gnu.org/gnu/ncurses/ncurses-6.4.tar.gz

二. 交叉编译ncurses

        1.创建新的链接

cd /opt/sdk/ohos/native/llvm/bin

ln -s clang aarch64-linux-ohos-gcc

2. 修改config.sub文件，添加ohos系统支持：

4. 创建编译脚本build_ncurses.sh：

#!/bin/bash
  
set -e
 
if [ "$1" == "clean" ] || [ "$1" == "distclean" ];then
    make $1
    exit 0
fi
 
export OHOS_SDK_HONE=/opt/sdk/ohos
export OHOS_NATIVE_HOME=/opt/sdk/ohos/native
 
export PATH=$OHOS_NATIVE_HOME/llvm/bin:$PATH
 
export AR="$OHOS_NATIVE_HOME/llvm/bin/llvm-ar"
export AS="$OHOS_NATIVE_HOME/llvm/bin/llvm-as"
export LD="$OHOS_NATIVE_HOME/llvm/bin/ld.lld"
export RANLIB="$OHOS_NATIVE_HOME/llvm/bin/llvm-ranlib"
export STRIP="$OHOS_NATIVE_HOME/llvm/bin/llvm-strip"
export CC="$OHOS_NATIVE_HOME/llvm/bin/clang"
export NM="$OHOS_NATIVE_HOME/llvm/bin/llvm-nm"
export OBJDUMP="$OHOS_NATIVE_HOME/llvm/bin/llvm-objdump"
 
 
export CFLAGS="--target=aarch64-linux-ohos --sysroot=$OHOS_NATIVE_HOME/sysroot"
export CPPFLAGS="--target=aarch64-linux-ohos --sysroot=$OHOS_NATIVE_HOME/sysroot"
export LDFLAGS="--target=aarch64-linux-ohos --rtlib=compiler-rt -fuse-ld=lld -lunwind"
 
./configure --prefix=${PWD}/_install \
        --target=aarch64-linux-ohos \
        --host=aarch64-linux-ohos \
        ${EXTOPTS}
 
make -j$(($(nproc)*2)) && make install

5. 开始编译

编译成功后，把静态库拷贝到交叉编译工具链路径：

./build_ncurses.sh
cp _install/lib/*.a /opt/sdk/ohos/native/sysroot/usr/lib/aarch64-linux-ohos/

备注：中途如果有如下运行错误，可以忽略
 

mkdir -p /home/wxx/work/porting/ohos/ncurses-6.4/_install/bin
/usr/bin/install -c -s tic     /home/wxx/work/porting/ohos/ncurses-6.4/_install/bin/`echo tic|       sed 's/$//'|sed 's,^,aarch64-linux-ohos-,'|sed 's/$//'`
strip: Unable to recognise the format of the input file `/home/wxx/work/porting/ohos/ncurses-6.4/_install/bin/aarch64-linux-ohos-tic'
/usr/bin/install: strip process terminated abnormally
make[1]: *** [Makefile:219: install.progs] Error 1
make[1]: Leaving directory '/home/wxx/work/porting/ohos/ncurses-6.4/progs'
make: *** [Makefile:136: install] Error 2

三. 交叉编译minicom

1. 修改config.sub文件，添加ohos系统支持：

2. 创建编译脚本build_minicom.sh：

#!/bin/bash
  
set -e
 
if [ "$1" == "clean" ] || [ "$1" == "distclean" ];then
    make $1
    exit 0
fi
 
export OHOS_SDK_HONE=/opt/sdk/ohos
export OHOS_NATIVE_HOME=/opt/sdk/ohos/native
 
export PATH=$OHOS_NATIVE_HOME/llvm/bin:$PATH
 
export AR="$OHOS_NATIVE_HOME/llvm/bin/llvm-ar"
export AS="$OHOS_NATIVE_HOME/llvm/bin/llvm-as"
export LD="$OHOS_NATIVE_HOME/llvm/bin/ld.lld"
export RANLIB="$OHOS_NATIVE_HOME/llvm/bin/llvm-ranlib"
export STRIP="$OHOS_NATIVE_HOME/llvm/bin/llvm-strip"
export CC="$OHOS_NATIVE_HOME/llvm/bin/clang"
export NM="$OHOS_NATIVE_HOME/llvm/bin/llvm-nm"
export OBJDUMP="$OHOS_NATIVE_HOME/llvm/bin/llvm-objdump"
 
export CFLAGS="--target=aarch64-linux-ohos --sysroot=$OHOS_NATIVE_HOME/sysroot -I/home/wxx/work/porting/ohos/ncurses-6.4/include -I/home/wxx/work/porting/ohos/ncurses-6.4/install/include"
export CPPFLAGS="--target=aarch64-linux-ohos --sysroot=$OHOS_NATIVE_HOME/sysroot -I/home/wxx/work/porting/ohos/ncurses-6.4/install/include/ncurses"
export LDFLAGS="--target=aarch64-linux-ohos  -lncurses"
 
./configure --prefix=${PWD}/_install \
        --target=aarch64-linux-ohos \
        --host=aarch64-linux-ohos \
        ${EXTOPTS}
 
make -j$(($(nproc)*2)) && make install

3. 开始编译

./build_minicom.sh

编译成功后，minicom会在_install/bin/下生成。

四. minocom在OpenHarmony上的使用

1. 在windows下，通过hdc工具，把minicom和vt100拷贝到OpenHarmony系统

这两个文件，可以通过这里直接下载：minicom+vt100

hdc file send minicom /data
hdc shell chmod +x /data/minicom
hdc shell mkdir -p /data/terminfo/v/
hdc file send vt100 /data/terminfo/v/

2.运行minicom

minicom在hdc shell下操作不友好，可以通过串口调试进去操作 

setenforce 0
export TERMINFO=/data/terminfo                                               
export TERM=vt100
/data/minicom -D /dev/ttyS9
